Box Collider 2D

The Box Collider 2D is a Collider that interacts with the 2D physics system. It is a rectangle in shape with a defined position, width and height in the local coordinate space of a Sprite. Note: The selection rectangle is axis-aligned, with its edges parallel to the X or Y axes of local space.

プロパティ	機能
Material	Select the Physics Material 2D that determines properties of collisions, such as friction and bounce.
Is Trigger	Enable this if you want this Collider 2D to behave as a trigger. The physics system ignores this Collider when this is enabled.
Used by Effector	Enable this if you want the Collider 2D to be used by an attached Effector 2D.
Used by Composite	Enable this if you want this Collider to be used by an attached Composite Collider 2D. Note: When you enable Used by Composite, other properties disappear from the Box Collider 2D component as they are now controlled by the attached Composite Collider 2D. The properties that disappear from the Box Collider 2D are Material, Is Trigger, Used By Effector, and Edge Radius.
Auto Tiling	Enable this if the Sprite Renderer component for the selected Sprite has the Draw Mode set to Tiled. This enables automatic updates to the shape of the Collider 2D, allowing the shape to automatically readjust when the Sprite’s dimensions change. If you don’t enable Auto Tiling, the Collider 2D geometry doesn’t automatically repeat.
Offset	Set the local offset values of the Collider 2D geometry.
Size	ローカル空間でのボックスのサイズを設定します。
Edge Radius	Collider のエッジを囲む半径を形成する値を設定します。これにより、角が丸くなった凸型のCollider 2Dが大きくなります。デフォルト値は0(半径なし)です。
Layer Overrides	Expand for the Layer override settings.
	Layer Override Priority	Assign the decision priority that this Collider2D uses when resolving conflicting decisions on whether a contact between itself and another Collision2D should happen or not. Refer to its API page for more information.
	Include Layers	Select the additional Layers that this Collider 2D should include when deciding if a contact with another Collider2D should happen or not. Refer to its API documentation for more information.
	Exclude Layers	Select the additional Layers that this Collider 2D should exclude when deciding if a contact with another Collider2D should happen or not. Refer to its API documentation for more information.
	Force Send Layers	Select the Layers that this Collider 2D is allowed to send forces to during a Collision contact with another Collider2D. Refer to its API documentation for more information.
	Force Receive Layers	Select the Layers that this Collider 2D can receive forces from during a Collision contact with another Collider2D. Refer to its API documentation for more information.
	Contract Capture Layers	Select the Layers of other Collider 2D, involved in contacts with this Collider2D, that will be captured. Refer to its API documentation for more information.
	Callback Layers	Select the Layers that this Collider 2D, during a contact with another Collider2D, will report collision or trigger callbacks for. Refer to its API documentation for more information.
